You are super full of what ifs. How many top cars do you think are daily drivers, leave equipment in for more than a few monthsAt least 3 of the top SQ cars had it that way, didn't talk to anyone about durability, just sound. Something's gotta give at some point. I believe besides the paper fiber cone, scanspeak also makes wool fiber cones, not sure if that's more resilient. They'll also be in direct sunlight if the sun is really low. From other angles, it's covered by the pod and/or car's roof.
Truth is HT drivers are designed for home audio. You can't argue that fact. They are made to be in sealed enclosures.
